im new to web development, and it has been suggested that I learn silverlight.
I am learning .net, c#, MSSQL, CSS, photoshop, and I didnt know if silverlight would be a good addition.
I would appreciate any thoughts on it.
In my opinion it would be a good addition to your skills set. It does not have the reach that Flash has, but in 2days day and age I really dnt think people will mind installing the plugin. Especially it being from MS. And it will help increase the reach of silverlight.
It is better than flash coz you can code it in C#, a language you already know. So the only thing you must learn in the XAML code for the front end.
And once you know silverlight, you also know WPF. As it uses the same technology, just with WPF having more features/functionality. But the syntax is the same. So you could also build nice windows WPF applications
Thanks nightstalker - and for your many other replies
dkchapuis, Silverlight can be a great tool, as you already have some .NET experience it won’t take you much time to look towards the WPF / XAML system so it’s worth taking the effort to learn it to round off your knowledge. Generally if people ask between Flash and Silverlight which to learn I usually go with Flash as it’s more widely distributed and has some advantages, but it’s not going to take you a lot of time / effort there’s no reason not to learn it. 
since you have c# already in your list, it easy to learn Silverlight. you may able to use most of the c# codes directly in silverlight. Also silverlight allows to run multithreaded application on internet browser.
another advantage is you can process local file directly (for example if you have an image upload page, you can use silverlight to check the image size and dimension and do some resizing at client end before uploading it to the server)
